http://www.play-asia.com/paOS-13-71-9g-49-en-70-1pns.html Plays exactly like mario picross and is just as good if not better. On top of it you can doodle your own pictures that it will turn into picross you can transmit to your friends (localy, plus must have the game). Probably the best hendheld picross i've played so far.
I liked the SNES Mario Picross games somehow. I'd say its a bit too pricey though for a puzzle game. nice one
